Normal-temperature preparation method for ultrafine lung-regulating and cough-relieving powder and special bilateral airflow sieving machine thereof

Abstract

The invention discloses a normal-temperature preparation method for ultrafine lung-regulating and cough-relieving powder. The method comprises the following steps of: selecting bulk pharmaceutical decoction pieces of lily, dwarf lilyturf root, rhizoma pinelliae preparata, aster, liquoric root, thinleaf milkwort root-bark, common anemarrhena, coastal glehnia root, dried orange peel, indian buead and floatstone; smashing bulk pharmaceuticals into coarse powder at the normal temperature; uniformly mixing the obtained coarse powder according to a certain proportion, putting into a rod mill for smashing, conveying into a special bilateral airflow sieving machine through wind for sieving with a 500-mesh sieve, sieving to obtain powder of which the particle diameter is less than or equal to 25 micrometers, conveying the powder which is obtained by sieving to a cyclone aggregator through airflow generated by a draught fan for collecting to obtain finished ultrafine lung-regulating and cough-relieving powder; and collecting powder which is not sieved with the 500-mesh sieve, and conveying to the rod mill through a pipeline for smashing circularly once again. The method has the advantages that: the entire preparation process is performed at the normal temperature; the particle diameter of a prepared finished medicament is less than or equal to 25 micrometers, and the cell-wall breaking rate and the biological availability are greatly increased; and due to the adoption of the bilateral airflow sieving machine, the preparation process of the ultrafine lung-regulating and cough-relieving powder is simplified.

Description

technical field [0001] The invention relates to the field of veterinary drug preparations, in particular to a method for preparing superfine powder Lifei Zhike Powder at normal temperature; the invention also relates to a special two-way airflow sieving machine used in the method. Background technique [0002] The main function of Lifei Zhike Powder is to moisten the lungs, resolve phlegm and relieve cough. Lifei Zhike powder currently used in livestock is mostly coarsely pulverized powder, which has problems such as large dose, coarse dosage form, poor appearance, incomplete release of active ingredients, and low bioavailability, which seriously affects the quality and therapeutic effect of traditional Chinese medicine. [0003] Traditional Chinese medicine ultrafine pulverization technology is an update and development of traditional pulverization technology. It not only retains the advantages of traditional Chinese medicine preparation technology, but also injects new vit...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for preparing superfine powder Lifei Zhike Powder at room temperature, which effectively solves the problems of high energy consumption, difficulty in precise control of the maximum particle size of the drug, inability to continuously produce, and much dust in the production process, which exist in the current production. The prepared finished medicine has the effects of fast onset of action, good curative effect, high bioavailability, and less clinical dosage
